    Entry number 66114

    keyword=Charge asymmetry problem fixed


    I looked at the entry for the slope and the value was for HWP "in" so that's the reason of the drift which occurs during the night.

    The slope are corrected now but the feedback has to be done by "phone" since MCC moved the HWP by hand. To come back to a automatic feedback, they need to restart their software to use the epics values we send. So the things will stay like this all over the week-end I guess, they don't want to call somebody during the week-end for that.

    So shift workers just has to give the value of charge asymmetry to MCC in case of big drifting and they will take care of the position of the rotatable HWP.

    When It will be possible to come back to automatic rotation (probably monday morning) we can restart the automatic feedbacks.
